Subject: [PATCH] net: phy: mscc: make arrays static, makes object smaller
From: Colin Ian King <colin.king@...onical.com>
Don't populate const arrays on the stack but instead make them
static. Makes the object code smaller by 1058 bytes.
Before:
text data bss dec hex filename
29879 6144 0 36023 8cb7 drivers/net/phy/mscc.o
After:
text data bss dec hex filename
28437 6528 0 34965 8895 drivers/net/phy/mscc.o
(gcc version 9.2.1, amd64)
